Outline

1	Fungi
2	"Fungi are heterotrophs who feed..." Fungi are heterotrophs who feed by absorption. They secrete digestive enzymes outside of their cells where digestion occurs, then they absorb the nutrients through their cell walls “Saprophytic feeding” Important as decomposers.
3	Decomposers
4	Hyphae and Mycelium
5	Septate hyphae vs “Coencytic”
6	Haustoria
7	Fungal Reproduction
8	"Sporangia on sporangiophores" Sporangia on sporangiophores Conidia on conidiophores
9	Fungal Reproduction
10	Fungal Reproduction
11	Origin of the Fungi Fungi descended from an aquatic, single-celled, flagellated protist. The fungi, animals and their protistan relatives form a clade called “Opisthokonts”
12	Origin of the Fungi Fungi have radiated into a divers set of lineages.
13	Fungal Taxonomy Chyridiomycota Zygomycota Glomeromycota Ascomycota Basidiomycota
14	Chytridiomycota Mainly aquatic Some Sprobes others parasitic Flagellated zoospores – only “fungal group with flagella. Cell walls Chitin
15	Zygomycota Rhizopus stolonifera
16	Life Cycle of Rhizopus stolonifera
17	Rhizopus sp.
18	Glomeromycota These are the “arbuscular mycorrhizae” The tips of the hyphae push into the cells of plant roots forming a highly branched “arbucle”
19	Ascomycota Sac fungi – sexual spores produced (meiosis) in an ascus (asci pl.)
20	Life cycle of Ascomycota
21	"Meiosis occurs in the ascus" Meiosis occurs in the ascus
22	Penicillium sp. Conidiophores and cleistothecium
23	Apothecium
24
25	Yeast
26	Morchella sp.
27	Basidiomycota Sexual spores are produced in a basidium (basidia pl.)
28	Life cycle of Basidiomycota
29	Basidiocarp (mushroom)

32	Lichens Symbiotic association of fungi (Ascomycota) and algae (greens or cyanobacteria).
33
34	Soredia
35	Mycorrhizae Mutualistic associations of plant roots and soil fungi.
36	"Fungus-gardening insects" Fungus-gardening insects
37	Predacious fungi Arthrotys sp. soil fungi traps nematodes.
38	Some fungi are pathogens Dutch elm disease
39	"Ergot – St Anthony’s Fire" Ergot – St Anthony’s Fire
